The answer is 3(-3-n) :) hope this helps
24 + 44 = 4(6 + 11) (Answer A)
4(12 + 22) ← 4 is not the greatest, 12 + 22 = 2(6 + 11)
6(4 + 11) ← this is 24 + 66
2(12 + 6) ← this is 24 + 24
Your answer is D.
Because there are no negative reciprocals, therefore there are no right angles.
a) 9 toilet rolls cost $ 4.23
1 toilet roll costs $ x
9x = 4.23 * 1
x= 4.23 / 9
x = 0.47
So in first case one toilet roll costs $ 0.47.
b) 4 toilet rolls cost $1.96
1 toilet roll costs $ x
4x = 1.96 * 1
x = 1.96 / 4
x = 0.49
So in second case one toilet roll costs $ 0.49.
0.47 < 0.49
The toilet roll in first case is cheaper than the toilet roll in second case.
Hope this heps!
